I have a site very similar to this one that also has ranks and details for various microstock agencies.

The url is http://www.microstockforum.com. Check it out if you have a minute. I am contacting all the stock sites to get image counts, member counts and compensation rates, etc.

BTW: Thanks for the other websites. I have been looking for some good keywording tools. I have been using Bridge and its to slow!
